Featured image for each article is blurry

Hi,

Love the IssueM plugin, but the ‘Featured Image’ for every article appears blurry on large (i.e. non mobile) screens. Performing a ‘save as’ on the image reveals why: the filename of the version that is downloaded contains the appendage ‘326×235’.

I have no idea why IssueM is deciding to stretch tiny 326 x 235 pixel versions of my images across the top of each article, instead of displaying the full-size versions that I upload without stretching.

Any ideas? All help, greatly appreciated.

Thanks,
Al
